' Application filed September s, 1903. Saris-1N0. 171,845.. (Remodel-T To all whom it may concern:

Be it known that I, ARTHUR T. BRADSHAW, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented anew and useful Cooking and Warming Apparatus, of which the following is a specification.

This invention relates to the preparation of food products, and has for its object to produce a device wherein the'food maybe cooked and afterward maintained at a proper temperature until required for use; and the inventlon consists in an inc oslng casing, prefand divided into independent compartments each provided with independent heating means,- and a. plurality of trays for the food receptacles adapted to be supported within one of-said compartmentsuntil the food is cooked and then transferred to another of said compartments and the food maintained therein'at the proper temperature until required for use.

, The invention further consistsin an inclosing casing divided into compartments each provided with independent heating-means, a

supporting-frame within one of said compartments and spaced from its walls, and itpllk' rality of trays forthefood-receptacle removably supported upon said frame until the food is cooked and adapted to be superimposed in another of said compartments and maintained .at the proper temperature therein until required for use.

ing casing divided into compartments each with independent heating means, a plurality within another of said compartments and the proper temperature maintained until the food I is required 'for use, and means whereby all but the lowermost of said trays may be sup-' ported .andythe lowermost tray removed without disturbing the remainder. 1

Other novel features of the invention will i appear in the annexed description and bespecified in the claims following.

In the drawings illustrative oi the inven -5 tion. Fig. 5 is a pe'rspective view from the front. Fig. 6 is.a perspective view from the rear. Fig. 7 is a transversesection on the line 7 7 of Fig. 1. Fig. 8 is a perspective" view illustrating the construction of the trayerably with walls of glass or similar material delivery mechanism. Fig. 9 is a view similar .to the left-hand. portion of Fig. 1, illustrating,

a modification in the construction of the traydischarging mechanism.

Fig. I 10 is a transverse; section of the construction shown in Fig. 9. Fig. 11 is a perspective view of'the tray-lowering rods shown 'in'Figs4 '9'and 10iI Figs. 12 and 13 are sectional details'illustrat 7 ing another modified form of tray-lo "weri'ngv v 1 Figs. 14, 15, 16, and 1'1 are viewsjin' devices. perspective of various forms. of trays for sup- 7 porting various forms of food hold'ing vessels This invention is designedmoreparticularly for use inwhat are-known as-guick-lunch?" restaurants, whereiuthefood is maintained in constant condition for use, but which may] likewise be employed in ordinaryrestaurants,v hotels, or for domestic purposes, and I do not,

therefore, wish'to" be limited in its use in any specific locality, but reserve "the right to v use wherever practicable! The invention further cons1sts in an lnclosthe purpose s ation an approved 'form of the apparatus,,such,as areflu'sedin 5 quick-lunch restaurants, is shown, and consistsof an outer casingor shell '10, preferably with-walls of glass or glass '-'like material, whichwill be easily cleansed and which, if of glass, will expose the interior of the casing 9 view.

The trays are designed to rest upon. the guide 'n'iei'nbers 24:. l and when thus arranged they are held upurt l so that the heating medium Will pass freely around all sides of each tray and come in con-- 1 tact equally with all the food-receptacles and their contents and thoroughly cook. them and for as long it period as required. When the 5 food upon any one ofthe treys is sufliciently l eoohechthet particular tray may be readily removed withoutdisturbing theothers. Thus l provision is made for treating different kinds or qualities of food products'which require different do Tens of heat or to be subjected to the heat for diiierent periods of time. In the cool;ing-compertinent having the hinged closures at both ends the trays may be inserted into or removed from the casing" from either side, will be obvious. lVithin one 1 of the remaining compartments another supporting-frame is disposed, consisting; or vertical members suitable horizontal members, and triinsverse members 33, This latter frame is designed to support the trays in the food in the receptacle thereon nus been teined until the food is required for use, and this temperature, as will be obvious, may be controlled by the valve 19. The function of the'studs 527 is to hold the trays separated when superinuiosed in the warmlog-compartmeet, so that the food-receptacles will not interfere, and also to permit free access of the heating medium toellparts. The lower most tray comes opposite the small closure l 17, so that if all the trays except the lowermost one be supported or elevated slightly the lowermost trey may be withdrawn through l the aperture 17. To thus elevate the upper l trays, vertical rods i tation in the frame-pieces and each provided 1 with projecting feet'36 37,- spuced apart l vertically upon the rods and disposed etright l angles to each other, as shown. The rods are also provided with oppositely disposed lugs 38 and the member 33 provided with stop-lugs $0, the stop-lugs being so disposed that when the lugs '38 engage the lugs 40 the feet 36 will be projected inwardly or into the pnths of the trays and the feet 3? turned into longitudinal alineinent with the members 33 und'of trays or outside 0 the paths of the letter. Then when the positions are reversed, with the stop-lugs 39 engaging the lugs .0, the feet 37 will he turned inwardly end the feet 36' outwardly, as will. be obvious.

' In Fig. 16 a tray is shown with two of the apertures 29 and food-receptacles arranged in a group of three, whiclymay beemployed for some kinds of food., InFig. 1.7 a tray is formed provided with a plurality of small pans 51, in which portions of meat may be cookedand maintained at. a uniform temperature, each'pan beingdesigned to hold enough meat for one sandwich, so=that ivhen a sandwich is ordered itcannbeserved lot. .i I, In Fig. 9 one of the trays is .shownfwit h tumbler-shaped 1'eceptacles .5 2, whichjwill be 100 found very convenient for cooking single eggs when ordered orother smal-l quantitiesotfood for small or individual. orders a Theframes 47 can beofany desired shape or size and of any material: which will meet the requirements. 7

I In Figs. 9, 10, and 11 a modification in; the manner of releasing thetray sin the warming. compartment isshown, consisting in asenies of rods 53 54, arranged in pairs, one pair-ad,- jacent to each corner of the supporting-frame and preferably extending upv through the casing 10. The rods are arranged to both,r.otate and move longitudinally in theframeand casing. The apertures in the vframe.member 33, through which the rods. pass, are;.elon gated, as at 55 56, and the rods arevpro-vid'ed,

IIO

respectivelynvith lugs '57, 58, 59, .60,;6;1,and

62. For the purpose of illustrationv a single pair of the rods are selected and designated by the reference character; but it will -beunderstood .each pair. are precisely-:alikeand operate in the same manner. W -hen the rods 54 are in their lowerposition,-as in @Figs. 9, '10, and 11, the lowerrelativelywide lugs62 5 will be opposite the second tray from the.-bot tom, so that ifthese rods bQltllIIlGdtOBXtGIld the lugs 61 transversely of the members 33 .4, ream ered to its place, the rods 54 will be rotated stillfarther to withdraw the feet 62 and the rods then returned to their former position and rotated to bring the lugs 61 transversely of the members 33 and the feet 61 across the vertical paths of the trays. The rods 53,- which have in the meantime been supporting the series of trays by their feet 59, are then rotated and the trays lowered until they rest upon the feet 62. The rods 53 are then rotated still farther to release their feet 59 from the trays and the rods moved upward to their former position and with the lugs 58 transversely of the member 33, which will move- ,the feet 59 into the path of the trays and beneath the third tray from the bottom, and thus sustain all the trays; but the lowermost two, as shown. .By this simple means the trays may be extracted one at a time Without disturbing the remainder. By this means the trays may be slowly lowered so as not to disturb their contents and may be employed when the trays contain liquid or other food products liable to be spilled.

.In Figs. 12 and 13' another modified form of tray-lowering means is shown consisting of pins or rods 63 64, adapted to be inserted through suitable apertures into the paths of the, trays, the pins arranged in pairs opposite the corners of the tray-frame and spaced to correspond with the spaces beneath the second and third trays from the bottom, as shown. By this simple arrangement the trays may be removed one at a time. as will be obvious.

In the foregoing description is shown the preferred form of the invention, but is not necessarily limited thereto, as modifications may be made therein without departing from the principle of the invention .or sacrificing any of its advantages, and the right is therefore reserved of making all the changes which may fairly come within the scope of. the invention and the claims made therefor.
